SIGNALS of Giant HII Regions: A Spatially Resolved Analysis of NGC 604
Ray Garner, Robert C. Kennicutt, Laurent Drissen +6
Observing giant HII regions at fine spatial scales uncovers detailed structures and reveals variations in ionization, abundance, and dynamical properties of ionized gas and the eff…
Ionized gas in NGC 4258: Exploring the AGN -- Star formation connection
D. Fernández-Arenas, L. Rousseau-Nepton, C. Robert +9
NGC 4258 is a prime target for studying feedback in Low-Luminosity Active Galactic Nuclei (LLAGNs) due to its proximity and comprehensive multi-wavelength coverage. Using new Integ…
WISDOM project -- XXIII. Star-formation efficiencies of eight early-type galaxies and bulges observed with SITELLE and ALMA
Anan Lu, Daryl Haggard, Martin Bureau +18
Early-type galaxies (ETGs) are known to harbour dense spheroids of stars with scarce star formation (SF). Approximately a quarter of these galaxies have rich molecular gas reservoi…
SIGNALS on the mixing of oxygen and nitrogen in the spiral galaxy NGC 6946
Fabio Bresolin, David Fernández-Arenas, Laurie Rousseau-Nepton +10
As part of the SIGNALS survey, which comprises a sample of approximately 40 nearby galaxies observed with the Fourier transform spectrometer SITELLE, we present a study of metal mi…
NGC 628 in SIGNALS: Explaining the Abundance-Ionization Correlation in HII Regions
Ray Garner, Robert Kennicutt, Laurie Rousseau-Nepton +5
The variations of oxygen abundance and ionization parameter in HII regions are usually thought to be the dominant factors that produced variations seen in observed emission line sp…
Properties of supernova remnants in SIGNALS galaxies -- I . NGC 6822 and M33
Salvador Duarte Puertas, Laurent Drissen, Carmelle Robert +4
We present a spatially resolved study of the kinematical properties of known supernova remnants (SNRs) in the nearest galaxies of the SIGNALS survey, namely NGC 6822 (one object) a…
WISDOM project XX -- Strong shear tearing molecular clouds apart in NGC 524
Anan Lu, Daryl Haggard, Martin Bureau +17
Early-type galaxies (ETGs) are known to harbour dense spheroids of stars but scarce star formation (SF). Approximately a quarter of these galaxies have rich molecular gas reservoir…
Ring nebulae around Wolf-Rayet stars in M33 as seen by SITELLE
Selin Tuquet, Nicole St. -Louis, Laurent Drissen +5
We have conducted an analysis of nebulae around Wolf-Rayet (WR) stars in M33 using data collected by the imaging Fourier transform spectrometer SITELLE at the Canada-France-Hawaii…
High-Spectral Resolution Observations of the Optical Filamentary Nebula in NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +18
We present new high-spectral resolution observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, the central galaxy of the Perseus cluster. These observatio…
Constraining the LyC escape fraction from LEGUS star clusters with SIGNALS HII region observations: A pilot study of NGC 628
J. W. Teh, K. Grasha, M. R. Krumholz +23
The ionising radiation of young and massive stars is a crucial form of stellar feedback. Most ionising (Lyman-continuum; LyC, ) photons are absorbed close to the stars tha…
Forming Stars in a Dual AGN Host: Molecular and Ionized Gas in the Nearby, Luminous Infrared Merger, Mrk 266
Damien Beaulieu, Andreea Petric, Carmelle Robert +5
We present star formation rates based on cold and ionized gas measurements of Mrk 266 (NGC 5256), a system composed of two colliding gas-rich galaxies, each hosting an active galac…
WISDOM project -- XI. Star Formation Efficiency in the Bulge of the AGN-host Galaxy NGC 3169 with SITELLE and ALMA
Anan Lu, Hope Boyce, Daryl Haggard +19
The star formation efficiency (SFE) has been shown to vary across different environments, particularly within galactic starbursts and deep within the bulges of galaxies. Various qu…
Stellar feedback in M83 as observed with MUSE -- I. Overview, an unprecedented view of the stellar and gas kinematics and evidence of outflowing gas
Lorenza Della Bruna, Angela Adamo, Philippe Amram +14
We present a large VLT/MUSE mosaic (3.8 x 3.8 kpc) of the nearby spiral galaxy M83, with a spatial resolution ~20 pc. We obtained the kinematics of the stars and ionised gas, and c…
